2 of 13
Adrenaline activates processes that increase the amount of oxygen and _______ to cells. This prepares the body for 'fight or flight'.
Glucose
3 of 13
Adrenaline causes the _____ muscle to contract more frequently with more force, thus causing the _____ rate and blood levels to increase.
Heart

Respiration
5 of 13
Adrenaline also targets the liver. It causes the liver to break down its ________ stores to release glucose (so there is more glucose in the blood).
Glycogen
6 of 13

Metabolic Rate
8 of 13
Which hormone plays an important role in regulating the metabolic rate?
Thyroxine
9 of 13
What part of the brain releases thyrotropin releasing hormone (TRH)?
Hypothalamus
10 of 13
TRH stimulates the _________ _____ to release thyroid stimulating hormone (TSH).
Pituitary Gland
11 of 13
What hormone stimulates the thyroid gland to release thyroxine when blood throxine levels are too low?
TSH
12 of 13
When blood thyroxine levels are too high, the hypothalamus is inhibited so no ___ is released. This stops the production of TSH, thus reducing the amount of thyroxine in the blood.
